    White usually means it is running Hot. Light brown usually means it is running Good. Dark brown usually means it is running rich.

    No, you are running Lean. White or Gray is Lean, Black is Rich.

    You want it to be a nice Beer Bottle Brown Color.

    You are not going to be able to tell if it is rich or lean by the plugs. These sc 4 tecs always look lean by the plugs even when A/f is perfect.

    agred leave the plug color reading for the 2 strokes as the 4 strokes always burn white.

    Exactly. Your plugs in your 4-Tec should always look bleached white if your ski is running well.
